Referring to the drawing the cap device is shown as applied to a collapsible tube, but it is equally applicable to bottles and sprinkler con- It consists of a stem or plug portion I in the form of a hollow cylinder threaded internally as at 2 in Fig. 3 for attachment to the threaded neck of a collapsible tube 4. Integral with this cylindrical neck is a flanged top 5, the upper surface of which may be convexly 'or concavelycurved as shown in Figs. 1 and 5 respectively, or it may be a piane surface. The periphery of this flange may be polygonal, circular or other suitable orna- The stem I is slotted diametrically at its upper end, and the slot 6 is partly,

or may be wholly contained within the lower face oi the flange 5.

lower face 8 of which is a single plane face against which is tightly pressed a washer 9 of cork, rubber or other suitable material interposed between the slide l' and the rim of the threaded neck 3 of the. container 4. It will be seen that by tightly threading the stem I upon the neck 3 that the slide i will be frictionally gripped with in the cap and therefore will not be sufiiciently loose to slide'unintentionally. The upper face of the slide 7 is formed for about half its length with a thickened part la, the longitudinal vertical walls of which are stepped narrowly inwardly relatively to the bwe part of the slide as indicated at lb. This thickened part 'la forms an oblong or square block which fitsfaccurately within a correspondingly shaped bayor opening iii cut in the'flange 5, the inner edge lea of this opening iii being disposed immediately. above a central orifice 9a formed in thewasher 9. Normally the inner vertical Wall To of the block 1a abuts against the said inner edge we of the opening l8 consequently a close sealingaction is obtained preventing extrusion of the contents of the container. When it is desired to extrude such contents the slide is pushed in the direction required to separate the opposed edges 10 and Etc. This push is effected by pressing in the end id of the slide l which is remote from the block la, such end id normally projecting a slight distance beyond the periphery of the flange 5 so as to be accessible for such purpose. A shortdistance'from thisend 1d the upper face of the slide i is very shallowly stepped downwards as at le to afford an abutment adapted to engage against a corresponding step 611 formed in the slot .By this means the slide 'ifcann'ot be completely pushed through the cap and will not be lost. This is an advantage over existing caps which have to be removed to enable the contents of the container to be extruded. V V

Thepushing in of the end 1d of the slide brings opposite the orifice to an aperture 1 in V the slide. This aperture is normally spaced from The aperture if is preferably of oblong form as shown when the device is intended in the closed position.

for use with .a tooth paste tube, as by this means a ribbon of paste can be extruded on to the top of the flange 5. However a circular or other suitably shaped aperture may be adopted.

The amount of sliding movement imparted to the slide need only be quite small, e. g. one tenth of an inch for use with a tooth paste tube, and this results in the slide being firmly supported when in the open position.

The upper surface of the'block la is'shaped so as to be in continuity with the upper surface of the flange 5 so that when the slide is closed there 7 are no external crevices within which paste or other material is trapped. Also the action of V closing the slide will cleanly sever the ribbon of tainers, e. g. tins for liquid polishes or powders. 1

paste, and a tooth brush, shaving brush, polishing rag or other utensil can wipeofl the extruded paste cleanly from the flange without waste and without leaving any deposit on the flange.

The formation of the slots 6 in the caps when being moulded can be effected by sliding plates 52 'male element it of the mould carries a plurality of bosses l'l adapted'to entercorresponding recesses l8 of the female part 13, these-bosses ll being concentrically recessed as at l e to form the stems l of the caps.

The present invention obviates the need for a slot or port in the cap, in which slot or port cream or liquid can remain exposed to the air andto pollution by atmospheric impurities. The device The of thefslide shall not project when the latter is To satisfy this demand, the diameter of the'disc may be increased and the periphery of the'disc may be notched, so that V the end of the slide, which otherwise would proiect, resides in this notch, or, the disc may be formed with a recess in its thickness so that the end of the slide, when in the closed condition,

' will be completely housed within the disc and not exposed to damage or breakage. By the construction above described, the slide is perfectly guided and stopped and prevented from any movement other than a sliding movement. Should the slide become damaged and jammed by extremely rough usage, it is nevertheless possible to unscrew the fitting in order to obtain dis-' charge of the contents of the container.

The flange 5 can be eliminated by having a thicker stem portion I, the top of the cap having its ;edge bounded by the periphery of the stem portion I. This would be suitable for caps for bottles.
